<br><font size=2 face="sans-serif">Okay you also need to reset bounds</font>
<br>
<br><font size=2 face="sans-serif">i.e.</font>
<br>
<br><font size=2 face="sans-serif">for (k=0;k<10;k++)</font>
<br><font size=2 face="sans-serif"> Solver->setColBounds(k,l[k],u[k]);</font>
<br>
<br><font size=2 face="sans-serif">Osl modifies bounds as part of branch
and bound.</font>
<br>
<br><font size=2 face="sans-serif">** Again this is a question which
brings up a) should there be a branch and bound in Osi and b) We do need
some coherent philosophy on what changes mean what.</font>
<br>
<br><font size=2 face="sans-serif">By the way I modified Sbb to use a save
solution but as Tobias mentions we now are running into Cgl conflicts.</font>

I get a solution (actually the same as the original solution [0 0
0 1 0 0 <br>
1 0 0 0]) with objective value 33 (also after <br>
addingSolver->setDblParam(OsiDualObjectiveLimit,1.0e50); ) . <br>
<br>
However there is a better solution [0 0 0 0 0 0
1 0 1 0] with <br>
objective value 75.<br>
